Glaucoma refers to a medical condition that affects the optic nerve, which plays a crucial role in transmitting visual information from the eye to the brain. The optic nerve comprises multiple nerve fibers that function similarly to the wires in an electrical cable. When an individual develops glaucoma, the nerve fibers in the optic nerve get damaged, which leads to vision loss.



What Causes Glaucoma?

Glaucoma, a common eye disease, is primarily caused by the blockage of the drainage angle through which aqueous humor circulates inside the front part of the eye.

Aqueous humor is responsible for maintaining healthy pressure inside the eye. It is produced in small amounts, while an equal amount is drained out through a microscopic drainage system. This drainage system is separate from the tears present on the outer surface of the eye.

In case the drainage angle is blocked, the excess fluid fails to drain out, leading to increased fluid pressure inside the eye. As a result, the optic nerve is subjected to pressure, causing damage to it. The eye is a closed structure. If the drainage area is blocked, which can lead to severe conditions that demand immediate attention from the best glaucoma specialist in Mumbai.

What Are The Different Types Of Glaucoma?

  1. Open-angle Glaucoma

    This type of glaucoma is the most common type, which accounts for about 90% of the total cases. It occurs when the drainage canals in the eye become clogged over time, leading to an increase in eye pressure. Open-angle glaucoma develops slowly and often goes unnoticed until it reaches an advanced stage.

  2. Angle-closure Glaucoma

    This type of glaucoma occurs when the iris (the colored part of the eye) is pushed forward, blocking the drainage canals and causing a sudden increase in eye pressure. Angle-closure glaucoma is a medical emergency and requires immediate treatment to prevent permanent vision loss.

  3. Normal-tension Glaucoma

    In this type of glaucoma, the optic nerve is damaged even though the eye pressure remains within the normal range. The exact cause of normal-tension glaucoma is not known, but it may be related to poor blood flow to the optic nerve.

  4. Congenital Glaucoma

    This type of glaucoma is very rare that usually occurs in infants and young children. It is caused by a developmental defect in the eye's drainage system, which leads to increased eye pressure and damage to the optic nerve. Congenital glaucoma requires prompt glaucoma treatment to prevent vision loss.

  5. Secondary Glaucoma

    This type of glaucoma occurs as a result of another underlying condition, such as injury, inflammation, or medication use. This condition can be either angle-closure or open-angle glaucoma. It is important to get regular eye exams to detect glaucoma early, as early diagnosis and glaucoma treatment in Mumbai can help prevent vision loss.

Symptoms of Glaucoma


Glaucoma, in its early stages, may not have any noticeable symptoms. However, as the disease advances, the following symptoms may arise -


  • Vision loss, particularly in peripheral vision

  • Blurred vision

  • Halos around lights

  • Eye pain

  • Nausea or vomiting

  • Severe headache

  • Severe eye pain

  • Eye redness



If you experience any of the aforementioned symptoms, it is imperative that you contact the best glaucoma specialist in Mumbai without delay. Delay in treatment of this form of glaucoma can lead to permanent blindness.

Note that 2⁄3 of individuals with closed-angle glaucoma may develop it gradually and without any symptoms before an attack occurs. Therefore, it is crucial to seek immediate medical attention if you have any of the aforementioned symptoms.
